The exact numbers aren’t clear, but we do know the following:
- The maximum increase, if a player has 100 Team Chemistry and 10 Individual Chemistry, is a total of 90 attribute points, spread out according to the player’s Chemistry Style (even if they just have the Basic one, it’s still spread across specific attributes).
- The maximum decrease, if a player has 0 Team Chemistry and 0 Individual Chemistry, is a decrease of 25 points in every attribute.
- Attributes start increasing at 5 Individual Chemistry and decreasing at 3 Individual Chemistry, staying the same at 4. It’s not entirely clear, at this point, how the hidden Overall Chemistry players into that.
